I have a concept ready for a brand-new mobile application and need it built natively for both iOS and Android—or via a robust cross-platform stack such as Flutter or React Native if that proves more efficient. The core of this job is the complete development cycle: polishing the UX/UI from my wireframes, writing clean and well-documented code, integrating required APIs, and preparing the builds for App Store and Google Play submission. When you respond, the single most important thing I need to see is past work that demonstrates you have taken an app from idea through launch. Links to live apps, GitHub repositories, or short videos of features in action will help me understand your style and code quality. Once we agree on the scope, I’ll share the full feature list and any brand assets so you can begin with a clear roadmap.
